How can addition properties help me add whole numbers

Mathematics
1 answer:
Bas_tet [7]2 years ago
3 0

Answer:

There are four addition properties that help to add whole numbers :

For any  whole number a, b, and c ;

1. <u>Closure property of addition </u>-   a+b

For example:

2+3=5

4+3=7

We can conclude that if we add any two whole number , we get another whole number.

2. <u>Associative property of addition</u>- when any whole number or variable are added, then that can be grouped in different way without changing result

a+(b+c)=(a+b)+c

For example:  

2+(3+4)=(2+3)+4

3.<u> </u><u>Commutative property of addition</u>- when any  whole number or variable are added, then the order changed without changing the result.

a+b=b+a

For example: 2+3=3+2

4. <u>Identity property of addition</u>- when 0 is added to a whole number or variable , the result is the same variable or number.

a+0=0+a

For example: 3+0=0+3

0 is called an Identity for addition of whole numbers.

You open a drink stand where you sell coffee and hot chocolate. You sell coffee for $1.80 and hot chocolate for $3.15. At the en
Usimov [2.4K]

Answer:

c = 69 and h = 51

Step-by-step explanation:

You will need two different equations here

use variable c as coffee and variable h as hot chocolate

c + h = 120

1.80c + 3.15h = 284.40

By moving variables, you can alter the first equation

h = 120 - c

Now insert this into the second equation

1.80c + 3.15(120 - c) = 284.40

Multiply

1.80c + 378 - 3.15c = 284.40

Subtract the c

-1.35c + 378 = 284.40

Subtract 378 from both sides

-1.35c = -93.6

Divide both sides by -1.35

c = 69

Then plug into the first equation

69 + h = 120

Subtract 69

h = 51

Write the y-intercept of the graph of 9x + 6y = 27
stealth61 [152]

Answer:

y= −3 /2 x+ 9/ 2

Step-by-step explanation:

Let's solve for y.

9x+6y=27

Step 1: Add -9x to both sides.

9x+6y+−9x=27+−9x

6y=−9x+27

Step 2: Divide both sides by 6.

6y /6=−9x+27 /6

y= −3 /2 x+ 9/ 2

Answer:

y= −3 /2 x+ 9/ 2
